Abstract:
... As much as grain cleaning is carried out before storage, it is not feasible to completely remove all impurities, and part of them are still present during the loading of the grains into the storage bin. Grain loading into silos and storage bins is carried out using an equipment called grain spreader, which can vary its shape and size according to the volume of grains. The main purpose of using gra ...

Abstract:
... A wide range of species relies on heterospecific visual cues to detect the location of resources like food. Although different hypotheses have been suggested to explain the emergence of this capacity in animals, results are often difficult to interpret due to the influence of other factors, such as close contact with humans. In this study, we presented eight Southern ground-hornbills (Bucorvus lea ...

Abstract:
... Municipal solid waste (MSW) composting is one of the most effective strategies for MSW management but detrimental litter such as plastic and glass debris must be discarded elsewhere. Well-segregated wastes are necessary in this context. A compost bin is a waste collection tool for source separation. To date, the deployment of compost bins for source separation has received scant investigation. Thi ...

Abstract:
... Radical chemistry and host–guest chemistry have each developed rapidly over the past decades and their intersection offers an attractive opportunity for modern applications. Radicals can be introduced into the frameworks of supramolecular hosts or radicals can be guests, generated in and confined to host containers. In this highlight we outline research achievements in both approaches, photoinduce ...

Abstract:
... Dry-off is a typical management practice, but research on the effects of dry-off on feeding behavior in high-yielding cows is limited. The present study investigated the effects of 2 diet energy densities: lactation diet (normal energy density, NORM) versus a lactation diet diluted with 30% straw (reduced energy density, REDU), both offered ad libitum, and 2 daily milking frequencies (2× vs. 1×) d ...

Abstract:
... Triboelectric charging and electrostatic interactions are commonly encountered in many powder handling processes. In this paper, the electrostatic behaviours of particles in a rotating spherical container were examined, in particular, the electrostatic dispersion of particles was recorded with a camera and then quantitatively analysed. The effects of the Coulomb's repulsive force and the attractiv ...

... The objective of the current study was to determine the relationship of daily CH₄ emissions estimated during mealtime compared with measured daily CH₄ emissions, and determine the relationship with feeding behavior, in growing heifers fed alfalfa silage in respiration chambers. Data from 8 growing cattle (Hereford × Holstein-Friesian) individually housed in 4 respiration chambers and fed ad libitu ...

Abstract:
... Grain dust represents a significant health risk to grain farmers and workers. Exposure to grain dust can diminish lung function as well as cause respiratory diseases. Grain storage facilities are considered agricultural confined spaces with high concentrations of grain dust. On-farm research for dust sample measurements is time consuming and cost prohibitive. The objective of this research was to ...

Abstract:
... Reusing packaging and containers can significantly reduce plastic waste, yet little research has considered whether people are willing to reuse containers, especially as they start to show signs of use. The present research developed a novel method for identifying how worn or dirty a container needs to be before people become unwilling to reuse it and demonstrates how this paradigm can be used to ...
... Outbreaks of African swine fever virus (ASFv) and porcine epidemic diarrhoea virus (PEDv) have revealed the susceptibility of livestock to disease transmitted through feed. Several viruses, including PEDv, survive in feed and may introduce disease that causes significant morbidity and mortality. In 2013, PEDv, which causes severe diarrhoea and vomiting, reached North America after spreading for de ...

... A photoresponsive diarylethene was incorporated in an achiral helical foldamer container. A carbohydrate guest was found to induce opposite handedness upon binding to the open and closed forms of the diarylethene-containing foldamer, thus enabling chiroptical switching of an achiral host mediated by a chiral guest. ...

Abstract:
... Household drinking water quality is dependent on a number of determinants which could be arising at the source, during transportation or due to storage and handling practices. The challenge of unsafe water is even big in urban settings that are often characterized by exponential population growth, increased urbanization, industrialization and poor sanitary facilities. Contaminated water is a leadi ...

Liquid marbles (LMs) are non-wetting droplets coated with particles, and these features highlight their potential as microreactors. However, sophisticated experimental designs are typically hindered because it is difficult to obtain sufficient substance m ...

The CTE–KDE approach is evidence‐based that identifies, and documents activities. It can be easily performed by (i) auditors; (ii) food manufacturers/processors; (iii) food suppliers to access gaps in process and supply chain. For example, for a ...

The aim of this study was to investigate the use of signal processing to detect eructation peaks in CH₄ released by cows during robotic milking, and to compare recordings from three gas analysers (Guardian SP and NG, and IRMAX) differing in volume of air sampled and response time. To allow comparison of gas analysers using the signal processing approach, CH₄ in air (parts per million) was measured ...

A novel solar assisted heat pump (SAHP) system for in-bin grain drying was proposed to solve the problems of poor uniformity and long drying time of grain in depot with higher initial water content in high grain piles. The effects of different operational parameters on the drying performance were numerically and experimentally investigated. The experimental results indicated that the thermal effic ...
